To all whom t may concern: l

Be it ,known that l, Ganar El. Doniuarmr, a citizen of the UnitedStates, residing at Troy, county of Rensselaer, State of New York, haveinvented certain new and useful Improvements in Electrioliighting Fix#tures, of 'which the following is a specification.

My invention relates to new and useful improvements in electriolightingfixtures, and more particularly of that character or type adapted tosupport an electric lamp on a work bench, table or other support, or inoperative relation to the same, although the invention is capable of usein other situations Wherever applicable.

The invention consists in the novel construction of parts, and thearrangement thereof in operative combination, to be more fully describedhereinafter, and the novelty of which will be particularly pointed outand 'distinctly claimed.

I have fully and clearly` illustrated two embodiments of my invention,in the accompanying drawings, to be taken as a part of thisspecification, and wherein-n Figure 1 is a View in front elevation of alighting fixture embodying my invention;

Fig. 2 is a section on the line 2-2 of Fig. 1; A

Fig. 3 is a detailed. view of one of the elements shown in Figs. `1 and2;

Fig. 4 is a detailed view in front eleva tion of a modification of thestructure shown in Fig. 3.

Referring to the drawings by characters of reference:

1 designates a distributing or outlet box,

tom horizontal walls 3, 4, parallel to each other, and at right anglestosaid rear wall,

I and vertical end walls 5, 6, parallel to each other and at rightanglesto said rear wall and said top and bottom walls. may be made of metal orany suitable 'material. The front of the box is provided with an opening7, adapted to be closed by a removable cover plate 8, preferably ofporcelain or other insulating material. The

cover plate 8 is held in position to close said opening 7 by means offastenmg screws 9, let through suitable openings 9 m said plate, andthreaded at their inner ends into This boxlugs 10 on the inner faces ofsaid walls 3, fl. 55

The plate 8 is provided with openings 81 for passage of electricconductors to the interior of the box.

.ln the form of the invention shown in Fig. 1, the bottom wall 4 of saiddistributing 6,()

or outlet box is provided with an external. downwardly projectingattaching device, preferably in the form of a cylindrical nipple 11,which is internally threaded at 12 to receive the threaded upper end ofa vertical standard 13. The standard 13 may be, and preferably is,provided with a sxiitable base or foot 111 adapted to rest on and besecured to the work table or other support indicated generally at 15.The standard 13 may, orA 70 may not, be tubular, according to whether ornot it is employed as a conduit for electric conductors. The nipple 11is preferably held in place on the wall of the box by inserting one endof said ni )ple throughian opemngfia in said wall, an swaging orexpanding said thread on the inner face of said wall, as indicated at11n in Fig. 2 of the drawings.

The end 'walls of the box are each pro- 80 end wall, and swaging orexpanding said end over on the inner face of said wall, as indicated at16EL in Figs. 1, 2 and 3 of the drawings. lThese nipples 16 'areinternally threaded as at 17 to receive the threaded ends of horizontalmembers 18, 19, respectively, preferablyvin the form of pipe sections oriat tubular members. T he opposite end of the member 19 from that whichis connected to the box 1 is connected to a vertical standard 2O bymeans of-the angle 95 nipple or coupling 21 at the upper end of saidstandard, thclower end of the standard having a foot 22 to rest on thetable 15, or other support. The opposite end of the member 18 from thatconnected to the nip- 100 ple 16 may be likewise connected to a supportor standard (not shown), similar to 'the standard 20, ormay be connectedto the nipple 16 of another box 1 (not shown) similar to the box 1heretofore described. 105

ficient and simple means for supporting one or more of said boxes atdesired intervals along a work bench or table'.

Projecting upward from the top wall 3 of the box 1 is a cylindricalbearing pin or stud 23,' which may be tubular it' desired, and securedin place on said wall by passing an end of the stud through an opening 3in the Wall and swaging or expanding said ends over on the inner face ofsaid wall at 23th At this point I would state that the particular mannerdescribed for securing the nipples 11, 16, and the stud 23 on therespective walls of the box 1 is preferable and eiiicient, but is notobligatory, as other means may be employed for the purpose withoutdeparting from the spirit and scope of my invention.

24 designates a swivel bracket comprising angularly disposed members 25,2G, preferably disposed at right angles to each other, and eachincluding a split sleeve, the arms 0r members 21, 25, of which areprovided at their free ends with apertured ears 27, 28, respectively,and apertures of which receive adjusting or clamping screws 29, 30, bywhich the arms of each member may be adjusted toward and away from eachother. The opening between the arms 25 of the member 26 is adapted toreceive the said bearing pin `or stud 23, and the arms aie adapted totightly engage the said pin, the degree of engagement being determinedby adjustment of the screw 30, whereby the bracket member is rotatablyadjustal/e or movable about the said pivot member or stud 23, so that itmay be turned on the latter and will be frictioiially held in the.position to which it is adjusted. The arms 2l of the member 25 areadapted to receive a cylindrical pivot member or pin 3l., carried on therear face of the part 3l, having oppositely disposed arms 32 carryingapertured guide sleeves 33 in alinetiient with each other, and throughthe apertures of which is Slidably and rotatably carried a supportingmember, preferably in the form of a rigid tube 35, at one endlof whichis carried a. key socket `36 for an incandescent lamp bulb 37. Theconductors 38 for the lamp preferably pass through one or more of thevertical standards 13 or 20 and within the outlet box, and are connectedwith the lamp by flexible conductors 39 passing through one of theopenings 8, heretofore described, and which are inserted in the rear endof the tube 35, thropgh which they pass to the lamp socket, as s iown inFig. 1.

The arms 24: of the member 25 are clamped in strong frictionalengagement by means of the screw 29, with the said pin 31 So that theniember31 may be adjusted pivotally, but will be held in any position towhich it is adjusted.

It will be Aseen from an examination of horizontally rotatable on themember 23 to 'provide for lateral or rotary adjustment of the lamp bulbabout the longitudinal vertical axis of the standard 13, and therotation of the part 31 on la horizont-a1 axis in lthe vertical member25 of the swivel bracket provides for the vertical adjustment of thelamp bulb 37; that is the memf ber may be located at differentelevations.

In the modified forni shown in Fig. et the construction is substantiallythe same as that heretofore described, except that this l'orin isadapted to be used without individual support by means 0f a standardsimilar to the standard 13, and for'this reason the attaching device 11,or its equivalent, is omitted. This form of the invention is adapted tobe inserted at any point in the lower portion ot the member 31", sothat.

the part 31 will be prevented from slipping out of engagement with thepart 25. The A part 31 preferably extends below the upper edge of thesaid plug 23, as is clearly/shown in Fig. 2 of the drawings. If itdesired to remove the part 31 from ,engagement with the part 25, theplug may be screwed down into the pivot 23 until the upper edge ot' saidplug is low enough to permit movenient of the part 31 above the upperend of said plug in a direct-ion lengthwise of the pivot member 31. Theplug may have sockets 23d to be engaged by a Spanner wrench for screwingthe plug in and out of the pivot stud 23.

From. the above description taken in connection with the drawings itwill befseen that I have provided a siinpleand effective arrangement forsupporting the swivel membei' of the lamp fixture directly upon the.

outlet or distributing box, andl for supporting the latter withoutcumbersome anticomplicated` supporting means. It will also be seen that1 have provided an'ai'rangement wherein the electric feed wires orconductors leading to the distributing box are supported and concealedabove, and free from, the supporting table, so that there is nolikelihood of said conductors being inthe way of the subject matter of aseparate applicatioin' Serial No. 158,801, filed by me under date 0fMarch 31, 1917.
